HOT.AIR MOTOR.

To all whom it concern: a 7

Be it known that I, LLOYD D. FREELAND, afcitizen of the United States, residing at Halbrite, Saskatchewan, Dominion of Canhave invented a certain new, useful, and Improved Hot-Air Motor; and do hereby declare the following to be a full, clear, and exact description of the inventlon, such as will enable others skilled in the art to which it appertains to make and use the same 7 V .My invention relates to improvements in hot air motors and has special reference to improvements in fuel fonts for such motors and supported. Upon the-upper end of the and means for supporting the fonts in position. 1

This present invention was first disclosed in my co-pending application for patenton motor driven fans, filed -March 27, 1915, Serial No. 17 ,568, of which this application.

is a division.

The object of my invention is to provide simple and effective meansfor supporting the fuel font in position; to provide a font which can be readily and easily placedin position; to provide aifont supportwhich shall act automatically to receive and re tain the font when the motor base is placed thereon, and to providesimple meansfor releasing the font from the motor base.

My'invention consists in the several features of construction and in the combinations and arrangements of devices and parts by which I am enabled to attain the above mentioned andother objects and all as hereinafter described and particularly pointed out in the appended claims. 7

My invention will be more readily understood by: reference to the accompanying drawings forming part of this specification,

cylinder is'secured and supported the. crank shaft housing 3. s

Within the upper part 4 of the base 1, a thlnwalled cylinder 5 depends, which is in:-

cased by a guard 6, having acentral opening 7: in its lower end. of the slots 8. 7

. The lower part 9 of the base 1 isflared out to provide ample space to receive the fuel font 10, which is provided with acen- The'upper' enda base is provided with ventilating trally located burner 11 adapted to project through the opening and to heat the lOWer end .of the depending cylinder 5.

The font 10 is relatively shallow and relativelylarge in diameter and is adapted to be placed'within the base. from below. I

providev stop shoulders 12,preferably three thereof, uniformly spaced, and adapted to contact with the upper surface of the font to position the same within the base. I

For holding, the font in place against the stop shoulders 12, I provide two thin bent arms 13 which are curved horizontally to fit withinthe outer part .ofthe base and below a horizontal circumferentialshoulder 12, and are pivotally mounted atone end on the base." The opposite ends 14 of the arms are bent or formed upwardly to'providefinger pieces 15 adapted to project upwardly through the openings-.16 in the base; To pivotally mount the arms 13 onthe base I provide each thereof with a hole 17 adapted to receive a downwardly extending projection 18 secured upon the shoulder 12 of the base. These projections 18 are spread apart sufficiently to give space to insert a screw or bolt 19 in the base between them by whichscrew I secure-a crescent shapedguard 20 rig-idlyin place. a This guard member is also formed on a curve, and its free ends extend around the base in opposite directions and serve'to support the curved members 13 and to guide them in combination with the shoulder 12.

The freeends ltof the members 13 overlap each other as best shown in Fig- 2 so, that when the finger pieces 15 are pressed to ward each other the members 13 will be separated. These members are normally held at the inner limit of their movement by meansof a tension spring 21, which has tively, ofthe members .13.

of theirbeing pressed toward each otherby the spring 21 to hold the tank pressed against the shoulders 12.

' For the purpose of easily entering the font into the position within the arms 13, I'make the upper part 23 of the periphery of the font inwardly inclined or 'cone shaped,,as shown, making the upper diamewardly into the base or the base is downwardly upon the font.

' by merely placing the motor down overand' ter small enough to be received within the members 13- when they are at their inner positions and adapted to causethe members- 13 to spread as the font'is pressed upforced The construction of the font and the font holding arms 13 is such that the font can readily be entered into the base from below upon the font. i

The weight of the motor is suflicient to cause the arms 13 to be spread as theyslide down the upper coned or beveled periphery of the font and thus permit the entering of the font. Once the largest diameter of the font has passed the arms 13 the spring 21 acts to forcibly press the arms toward each other and lift the font into contact with the stop shoulders '12 by reason of the beveled lower portion of the periphery of the font.

After the font has been thus placed in position, it is securely held in the base and largest diameter of the font.

is portable with the motor.

To release the font it is only necessary to lift the motor 01f, first separating the arms 13 by pressing the finger pieces 15 toward each other so that the arms 13 will pass the As many modificationsof my invention will readily suggest themselves to one skilledin the art, I do not limit or confine my invention to the specific structures herein shown and described.

.Iclaimz' V e 1. In a hot air motor, a chambered base open at its lower end, a fuel font adapted to be received in said base through said open end, yielding means within the base for en-' gaging the font to retain it in 'thebase, and

I 2. In a hot. airmotor, a chambered base open at the bottom, a fuel font for placement within said base through said open bottom, arms within the base yieldingly held in font engaging position, and means projecting through the base for separating the arms to release the font.

3. In a'hot air motor, a hollow base open at its lower endfor receiving'a fuel font therethrough, a plurality of fuel font sup porting arms pivotally mounted within the base, and means yieldingly; holdingqsaid arms toward each other for supporting font.

e. In a hot air motor having a hollow base open at itslower end and'adapted to receive a, fuel font, a pair of font supporting arms each pivotally mounted at one end on the base and movabletow'ard and from each other to engage and disengage a fuel font, and a spring yieldingly holding said arms infont supporting position.
